Because the intermolecular bonds are not so strong.
When cooled gases change to liquids (usually) and then solids Solids don't change to gases upon cooling
Solids do not mix well because there shape can not change. But a liquid and a gas can change their form. For example- you can't just change the shape of ice, but you can change the shape of water. Hope that helps

Gases that are flamable Gases that can easily catch on fire There are numerous highly flammable gases. Some of the most common include butane, hydrogen, ethylene, methane, ammonia, acetylene, and propane.
Gases adopt the form of the container it contains an hasn't a constant volume.. A liquid adopt the form of the container it contains but has a constant volume. A solid has form and constant volume.
Gases adapt most easily to changes in volume.
A gas will undergo a change in volume more easily than either a liquid or a solid.
Gases undergo changes in volume very easily.solid
Diffusion of gases easily occurs across a membrane. The gases will have to be converted into liquids so as to diffuse easily.
This is a liquid. Note that the volume of a liquid will change a bit with temperature, but remains relatively the same. Also note that science teachers are fond of saying that a liquid takes the shape of its container, which is pretty much the same as saying it has no fixed shape.
Solids are the least able to be changed. Liquidshave their volume conserved, though the shape may change. Gases have neither fixed volume nor shape.

Light gases; Gases that are light weight will more easily reach escape velocity than heavier gases.
Solids do not mix well because there shape can not change. But a liquid and a gas can change their form. For example- you can't just change the shape of ice, but you can change the shape of water. Hope that helps

Yes. Usually when a substance freezes, or becomes a solid, it will decrease in volume, causing an increase in density. Water is an exception, which is less dense when it freezes/becomes solid.
This can be explained in terms of the kinetic molecular theory of gases. Due to the low density of gases, the particles are more widely spaced and so most of the volume taken up by a gas is empty space (as in any shaped container).
